LS9, Codexis land Presidential Green Chemistry Awards

June 21, 2010 |

In Washington, the EPA announced this morning the winners of the Presidential Green Chemistry Challenge Awards, and LS9 and a Codexis-Merck collaboration were among the winners.

LS9 is being recognized specifically for its revolutionary Renewable Petroleum technology that converts renewable raw materials into low-carbon fuels and chemicals.

Merck and Codexis were recognized for a biocatalytic method  for the synthesis of sitagliptin, the active ingredient in Merck’s diabetes medications,which  provides sitagliptin with a 10 to 13% increase in overall yield, a 53% increase in productivity (kg/L/day), a 19% reduction in total waste, the elimination of all heavy metals, and a reduction in total manufacturing cost; the enzymatic reaction is run in multi-purpose vessels, avoiding the need for specialized high pressure hydrogenation equipment.”

The awards, given annually by EPA on behalf of the White House, recognizes new technologies in five categories that help prevent pollution by reducing or eliminating hazardous waste in industrial production. Codexis also won the award in 2006. Last year, Virent was a recipient of the awards which were first established in 1996.
